first one python script:

Print ("Hello World")

[email protected] ~]# python helloworld.py

Hello World

Install python3 and ipython Overall environment, very troublesome, not pay attention will often error, installation is not successful, toss a day to fix, the process record as follows:

First step: Install python3.5

1. CentOS 6.5 Installing Python 's dependency package

Yum Groupinstall "Development tools"
Yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel Libpcap-devel Xz-devel

2. Download the Python3.5 source package and compile it

wget https://www.python.org/ftp/python/3.5.0/Python-3.5.0.tgz
Tar XF python-3.5.0.tgz
CD Python-3.5.0
./configure--prefix=/Application/python--enable-shared
Make
Make Install
Ln–s/application/python/bin/python3/usr/bin/python3

3. You need to configure the library before running Python:

Echo/usr/local/lib >>/etc/ld.so.conf.d/local.conf
Ldconfig

4. Run the Demo:

Python3--version
Python 3.5.0

5. Delete the libraries needed tocompile Python , of course, it can not be deleted

Yum Groupremove "Development tools"--remove-leaveas
Yum Remove Zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel L Ibpcap-devel Xz-devel--remove-leaves

6, set up aliases for easy use , or you can not set

Alias Py=python3

Step Two: Install Ipython3

1, need to install setup-tools

Address: Https://pypi.python.org/pypi/setuptools  

Decompression Unzip Setuptools-36.5.0.zip

CD setuptools-36.5.0

/application/python/bin/python3 setup.py Install

2. Install pip

Address: Https://pypi.python.org/pypi/pip

Tar XF pip-9.0.1.tar.gz

CD pip-9.0.1

/application/python/bin/python3 setup.py Install

A few folders named Pip pip3 pip3.5 are generated under /application/python/bin , stating that the pip The module has been packaged into a python environment.

3. Installing python-setuptools and python-setuptools-devel

Install with yum installation

4. Installing Ipython

Address: Https://pypi.python.org/pypi/ipython

Tar XF ipython-6.0.0.tar.gz

CD ipython-6.0.0

/application/python/bin/python3 setup.py Install

5. Configuring soft links or adding system environment variables

Ln-s/application/python/bin/python3/usr/bin/python3

Ln-s/application/python/bin/ipython3/usr/bin/ipython3

Ln-s/application/python/bin/ipython/usr/bin/ipython
